基于随机变换的大容量隐藏算法

主要研究利用图像低位平面数据位的运算来减小对载密图像修改的信息隐藏算法.在嵌入信息时对秘密信息进行连续多次随机变换的同时与载体信息进行位运算,以此求出对载体图像修改量最小的嵌入方式.从而实现在相同嵌入量的条件下尽量减少对载体图像的修改,提高了载密图像的质量.实验结果表明,该算法能有效地减少载体图像的失真,在嵌入大量信息...

Large capacity information hiding scheme based on stochastic transformation

This paper mainly studies the information hiding algorithm by using the image low plane data bits operations to reduce the modification of image which was loaded secret.In the process of embedding secret information to the cover image,the secret information was random transformed repeatedly and at the same time with bit operations so as to find out the way of minimum modification on the carrier images.This algorithm minimized the modification of cover images and improved the steo-images' quality.The experim...
